A large uploaded image is not saved properly after cropping in disabled CanvasMode. Instead of saving the cropped part of the image, the control is saving the original image resized to fit the cropped part size.

The issue is reproducible both by using the Save dialog (Save image on server) or the saveImageOnServer() method.

Steps to reproduce:

1. Open in IE8
2. Upload the attached image
3. Crop a part of it
4. Save the image on server

Result: The original image is resized with the crop-box dimensions.

For the time being you can hardcode the "touch-action:none" style to the ImageEditor:

<telerik:RadImageEditor ID="RadImageEditor" runat="server" style="touch-action:none;"></telerik:RadImageEditor>

The mouse position coordinates of the ImageEditor (can be seen in its bottom Statusbar) are not updated properly after zooming (Crtl+Mouse scroll over the image). Moving the mouse pointer outside the ImageEditor's viewport and bringing it back forces the control to recalculate the mouse position properly.


Steps to reproduce:
1. Open
2. Choose a specific point of the image and check its position (the x and y coordinates shown in the ImageEditor's status bar)
3. Zoom-in the image by pressing Ctrl and Mouse scroll
4. Navigate to the same point

Actual: The x and y coordinates are changed
Expected: The x and y coordinates of the point are the same as before the zooming

When a big image(~3MB) is loaded into the ImageEditor ( with enabled CanvasMode) sometimes the image is not loaded into the controls or the whole page crashes. The issue could be reproduced in Google Chrome, with the 2013 Q1 SP1 version of the controls.

Adding ImageEditor inside a RadPanel breaks the RadPanels designer. The problematic behavior can be observed with the following configuration:

        <telerik:RadPanelBar ID="RadPanelBar1" Runat="server">
                <telerik:RadPanelItem runat="server" Text="Root RadPanelItem1">
                        <telerik:RadImageEditor ID="RadImageEditor1" runat="server" ImageUrl="~/Images/Jellyfish - Copy.jpg"></telerik:RadImageEditor>
                        <asp:Button runat="server" ID="dasd" />
                        <telerik:RadEditor ID="RadEditor1" runat="server"></telerik:RadEditor>

When the command dialogs from two ImageEditors on a page are opened consecutively, the second dock is rendered with wrong position. The issue most probably comes from the fact the second dock element (ToolsPanel) is appended to its parent ImageEditor, but not to the form.

Assuring that each dock is appended to the form element can be used as a temporary workaround of the issue:

        <telerik:RadImageEditor ID="RadImageEditor1" runat="server" Width="680" Height="450" OnClientDialogLoaded="ClientDialogLoaded"
        <telerik:RadImageEditor ID="RadImageEditor2" runat="server" Width="680" Height="450" OnClientDialogLoaded="ClientDialogLoaded"
            function ClientDialogLoaded(imageEditor, args) {
                setTimeout(function () {
                    $telerik.$("#<%=form1.ClientID %>").append($get(imageEditor.get_id() + "_ToolsPanel"));
                }, 0);

When you set Lightweight render mode via web.config, the image editor appears broken.

You can use the following setup in web.config as a workaround for the time being. Note that all instances of the RadToolBar will be rendered in Classic mode.
      <add key="Telerik.Web.UI.RenderMode" value="Auto" />   
      <add key="Telerik.Web.UI.ToolBar.RenderMode" value="Classic" />
